Microsoft has revealed that Windows Mobile 7 - the next version of its smartphone OS - is unlikely to be released until "late 2010".
Phil Moore, UK head of mobility at Microsoft, said the OS has "been put back until late next year but it is definitely coming".
"You're going to see a lot more on Windows Mobile 7. Giving the enterprise users and consumers what they want will be part of Windows Mobile 7. You'll get flexibility on a much easier touch UI."
Microsoft released Windows Mobile 6.5, which it renamed Windows Phone, in October this year.
